HOOD LOCK Filed Feb. 24, 1931 Patented Aug. 9, 1932 JOHN C. ELLISON, OF GHICAGO, ILLINOIS;

HOOD LOCK Application, filed February '24, 1931'.

'Fhe invention relates to a hood lock-ofthe type-more'particularly for use on auton1obil'es toseourely hold theho'od of the car-in closed position- The present day: cars: asmanufactured are provide'chwith hood clamps for holding-the hood closed but not of thetype that maybe locked to renderit impossible for anyone not authorized? to" do so, to tamper with any of the parts under the-hood..

An object of'iny: invention isto construct ea-hood lock: that is simple in construction, effective-"in operation, of few parts and: inexpensive to manufacture.

Anotherobject is to provide a hood lock comprising two members, one being permanently secured to: the frame of a,car',.ands the othermember secured near the lower edge of the hood; of the car, so that when the hood is closed, the member secured to the frame may bepositively and securely locked to the removable member, thereby rendering it impossible to open the hood without the use of a key 4.

With the foregoing and other objects in View, which will appear as the description proceeds, the invention resides in the combination and arrangements of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made without departing from the spirit of the invention.

In the accompanying drawing Fig. l is a side elevation illustrating my device as attached to the frame and hood of an automobile.

Fig. 2 is a view similar to Fig. 1 showing the body of the device in section; Fig. 3 is a side elevaton of the device taken on line 3-3 of Fig. 1; Fig. i is a vertical sectional view on line l?l of Fig. l. 5 is a detail sectional view of a modified form of arm.

Referring to the drawing, the numeral designates the body or base, provided with the flanges 1111 adapted to be secured to the frame or hood plate 12. The body of the device is provided with an opening 13 extending vertically and reduced at the upper Serial No. 517,815.

end to provide an. opening 14. On opposite sides the body 10 is provided with elongated openings l5' l5', while the front and rear portion are provided. with vertical. slotopenr. ings 1'6 1 6;

A pail of; oppositely disposed arms on grippers l7.1- T are pivoted. ona short shaft 1 8 which is guided and slidably mounted. in the vertical? slotopeningsv 16'16v and extend: through the openings l5 of the body 10 and are yieldingly held atthebottom; of the slots l6il6-by a: headed plunger IQslidabl-y mounted inv theopeningld' and held in yielding contact against the arms l'7l:7 by: meansof a. compression spring interposedbetween the head of the plunger 19,- and the top wall of the body 10.

The arms or grippers 17.-17 are pivoted side by side on: the shaft; 18 and are eachp-rovided with: a hole or opening 251 spaced some distance; below the shaft 18, through which a pin orpllungerQZ o'fa lock; 28 extends when the openings register. Thelock 23 is-thread. ed or otherwise secured in the body 10:.

Each arm 1'1 is providedat its upper end with an inwardly extending portion 17a and an outwardly extending finger piece 11 6., The: inwardly extending portions l7 a of the arms 17, are adapted to, engage substantially channel shaped member- 25 secured to the hood 26 of a car, so that. when the hood is closed the channel shaped memr ber 25- will be brought into the path. of the arms l'Z- l;7 and spaced some distacev from the top of the body member 10"..

Assuming the arms 171-427 to be the per sition shown in dotted lines in Fig. 2,. the operator takes hold of the finger pieces 17 and liftsup, and in so, doing the plunger 19 compresses'the spring 20 so that when the arm is released, the projection l7.-a will be held in yielding contact with the channel member 25. A, flattened portion 27 is pro vided on the; arms 17 just above their pivotal poin 18 and is. engaged by the headed plunger L9to retain the arms 17rd,? an upright position.

The holes 21+21 in the 17 are below the pivotal point and when the arms. are in the position shown in, full linesFig. 2, the

plunger 22 of the lock 23 is projected into them to hold the arms permanently locked to the removable member 25.

On the member 25 I provide the lugs or projections 28 adapted to engage and fit into the recesses 29 to insure perfect alinement of the arms 1717 so that the openings in the arms will register and the plunger 22 of the lock 23 will be easily projected into the openings 2121 to lock the arms.

In Fig. 5 which illustrates a modified form of arm, I provide an inclined surface 30 on the hook or arm 17 so that the removable member 25 may be dropped into position and held by the arms under the tension of the spring as above described.

I claim: 7

1. A device of the character described, comprising in combination abody member, a pair of oppositely-disposed arms pivotally mounted in the body member, spring tension means coasting with said arms for yieldingly holding them in open and closed position, a removable member adapted to be held by said arms and a lock in the body member to engage the arms to securely hold them while they are engaged with the removable member.

-2. A hood clamp comprising in combination a base portion adapted to be secured to the frame of a car, a substantially channel shaped member secured to the lower edge of the hood of the car, a pair of oppositely disposed hooks pivotally mounted in said base portion adapted to engage the channel shaped member, a spring pressed plunger engaging each of said hooks near their pivotal point and a plunger lock fixed in the base portion adapted to engage each of said hook members adjacent their pivotal point.

3. A hook clamp comprising in combination a hollow body portion, having a base adapted to be secured to the frame of a car, a substantially channel shaped member secured to the hood of the car, a pair of upwardly extending arms provided with inwardly extending projections, said arms being pivotally mounted in vertical elongated slots and provided with a flattened portion above its pivot, a spring pressed plunger engaging the flattened portion of said arms to normally hold them in upright position to engage each edge of said channel shaped member'and a lock adapted to engage botharms to securely hold them in their upright position. 7

4. hood lock of the character described, comprising in combination a base portion,

said base portion having side walls provided with openings therein, a front wall, a rear wall, said front and rear walls having alined vertical elongated slots, a topwall integral with front and rear walls and said side Walls, a pair of upwardly extending gripping members, pivotally mounted in said elongated slots extending through the openings in the tending portions at their upper extremities adapted to engage a relatively short plate,

a spring pressed plunger engaging each of said gripping members near their pivotal point to yieldingly hold them in the elongated slots, finger pieces extending outwardly adj acent the inwardly extending portions and a keylock provided with a plunger adapted to engage the gripping members below their pivotal point.

5. A hood lock of the character described, comprising in combination, a hollow body member having openings in the sides thereof and elongated slots disposed in alined relation in the front and back thereof, a pair of arms pivotally mounted in theelongated slots, a'spring tension exerting a presser on each arm at their pivotal center to normally hold the arms yieldingly at the lower end of the elongated slot, said arms being provided with inwardly extending projections at their upper ends adapted to engage a removable member and lock means adapted to engage and permanently hold the arms in upright position while engaged with the removable member.

6. A device of the character described, coms prising in combination a body member, a. pair of arms pivotally and yieldingly mounted in the body member, spring means for yieldingly holding the arms in upright position, said arms having inwardly extending portions at the upper end thereof, a removable member adapted to be positioned between said arms, under the inwardly ext-ending portions and a lock in the body member adapted to engage both arms while the arms are normally upright.
